11:53 AM rue_mohr: wow, thats pretty good!
12:30 PM polprog: nice!
12:30 PM * polprog is back :)
12:39 PM aandrew: rue_shop2: that seems like a lot of work (custom toroid) for only 40% efficient and 250mW... is that really better than designing around a pulse transformer or some other common/stock tx?
12:51 PM rue_mohr: yea, I'm going to try some other things
12:51 PM rue_mohr: well, I want to use a custom one so I can use the same circuit and set the ratios to whatever I need
01:10 PM aandrew: I get the draw for a "popcorn" circuit that uses nothing proprietary and you just do whatever you want with the tx
